' To alli/whom 'itmcy concern: i

Beit known that I, Hanni' E. GREY, a citizenofthe United States, and a resident of Philadelphia, State of Pennsylvania, have invented certain new and useful '5, Improvements in Gaskets, of which the allowing-is s full, clear, and vcomplete disclosure. l i t I The object of m`y invention is to provide agasket formed einen-metallic and metallic packing materials so combined that the gasket' will utilize all of the desir- 10 able. qualities of each material. f, V Y with .thispbject in View, theinvemion consists in the novel construction `hereinafter described and claimed.v

In the accompanying drawings, `Figure l is4 a plan view of one side of a gasket constructed in accordance with I `thisfiixvention; Fig. 2 a plan 4view of the other side of Ilpth'e same, and Fig. 3 a sectional view of the sa'rnetaken on the vline 3-3 of Fig. 2.] f

i iReferring to the drawings, whichshow the particular 2O embodiment of my invention which I have selected to illustrate the same, :the packing ring or gasket 1, comprising anon-metallic `annulus 2, a metallic ring 3 covering substantially the outer half of one side of thc nonmetallic annulus, and having its outer edge folded over 2,5 and binding the outer edge of the same, and a metallic ring 5 covering the inner half of the other side-of theIk said annulus, and having its inner 'edge folded over and binding the inner edge of the annul'us, the louter edge .7 ofthe said inner 'ring 5 beingsubstantially in alinement with the inner edge 8 of the said outer 3. l The two rings 3 and 5 may be formed, without any loss of material from a single ring dividedI by a single cut extending along the edge 7 to form the inner and outer edges of the two separate rings, and furthermore by this construction the inner edge of `the outer 'v and the outerA edge of the inner may pass eachV ,other 'when the gasket is compressed, preventing the binding of the rings (me over the other, and the space between the adjacent edges oi the metallic rings being of non-metallic entire width. v

The advantages oithis constructinare that the gasket or ring presents n eontinuous metallic surface and alsoa continuous non-metallic surface upon each side material throughout substantially its at .both -edgesand prevents it from blowing out or from I' being pressed the metallic portionsalso protect the non-metallic portion from contracting withthe steam, gas, or other fluid or liquid surrounding it, and thus protect it from being burnedor eatenaway; andfurthermore the metallic portions protect the non-metal1ic por. tion from displacement or damage by vibration or exl., n pansionand contraction, due to change in temperature orsimi1arcauses. i

' In constructing this ring, either rubber, asbestos, leather, paper, fibrous material, or almost any compressible material may be used for the non-metallic portion of the ring; and copper, or any other similar material, may be used for the metallic portions., f

When the packing ring is to come in 'contact with acids, suitable acid resisting materials can be used in the construction; andthe materials in any'case may be selected in accordance with the nature of the work to be performed.

I do, not wish to limit myself to any particular metallic or non-metallic substance in this invention, and fur-` thermore, I.do not wish to limit myself to the combina tion ofV a metallic material with a non'metallic as the invention could'be applied to -a gasket, comprising a of a metallic binder, or both materials might be metallic,

'one being harder. and more tenacious than the other to act as a binder.

' I haveused the designations metallic and non-metallic simply to indicate a comparatively hard and a comparatively yielding materialand furthermore l do not limit myself to a gasket made in the form of a ring, as this invention could be applied to a gasket made in the form of a stripvdesigned to be laid straight or to bc wrapped between surfaces to be packed. I

Having thus fully described my invention, what I claim and desire to protect by Letters Patent is:

1. A gasket comprisingy a yleldlng body memberaud a less yielding binder-member overlapping the sides of sald body member, and presenting continuous surfaces of sold body member und of said bindermember upon euch side body member, and'presentlng continuous metallic and nonmetalllc concentric surfaces on each side of said gasket.

4. A gasket "comprising a metallic 'body member and a non-metallic binder member overlapping the sides of sald body member, and presenting contlnuousmetallic and nonmetalllc surfaces on each side of seid gasket, and having a metallic edge.

5.- A- gasket comprising anonrmetalllcfbody member und n a. metallic binder member overlapping the sides of snld .f the metalhc material binds theV non-metalhematenal body member; and presenting continuous non-metallic sur-y faces upon each metallic edgel I 6. A gasketcomprlsiiig'a nonm`etalllc body memberl and lndepedent metallic binder members-overlapping the sides 4of '-sald gasket,l und presenting continuous nou-metallic surfaces upon auch slde thereof, und having metallic inner and outer edges. l

v non-metallic body portion and a non-metallic instead *u i gasket and extendside of said gasket, said gasket having n 7. A gasket comprising a4 nommetalllc annular body member, a metalllc-coverlngfor said body extending upon one slde .thereof from its inner perlphery to a llne substantlnlly in idwl'ybetwsen ltlv inner and outer perlpheries, and

a separate metallic covering for theA opposite side of said body extending from its outer periphery inwardly to a line substantially opposite the outer edge of the inner cov ering.

8. A gasket comprising a non metallic ring, a metallic covering for said ring binding the inner edge thereof and extending upon one side to a line about midwaybetween the peripheries of the ring saidy ring presenting continuous surfaces upon each side of said gasket. l

9. A gasket comprising a non-metallic ring, a metallic covering for said ring extending upon one side from the inner edge thereof, and having its inner ,edge flanged and binding the inner edge of said ring, and a. separate me V inuerzportion ofthe opposite side of said non-metallic ring.

11. A gasket comprising :a non-metallic ring, a metallic 'ring covering the outer portion of one side of said nonmetallie ring, and a separate metallic ring covering the inner portion of the opposite side oi? said non-metallic ring.

12. A gasket comprising a non-metallic ring, a kmetallic ring` binding the outer edge of said gasket, and'extending over the outer surface of one side tlie'reof,and a` separate metallic ring binding the inner edge of"`said gasket and extending over the inner portion of the other side thereof.

13; A gasket comprising a body portion, and independent binder portions upon the edges and overlapping the sides thereof..

14. A gasket comprising a yielding body portion, und independent less yielding binders upon the edges and over-v lapping the sides thereof. .p

.15. A gasket comprising a body portion, and independent binder portions upon the edges and overlapping thesides thereof, fthe. surface of said body portion being exposed upon opposite'sides of the said gasket.

16. A gasket comprising av body portion, and independent binders upon the edges and overlapping the sides thereof, the said body portion being exposed upon each side of said gasket in a single continuous surface',

17. A gasket comprising a body portion and independen binders therefor, Saidbinders being located-on opposite edges and sides of the said body portion, and covering only a portion of each side.

18. A gasket comprising a yielding'body"y member, and 'a less'yielding binder member contacting with a sideand an edge of said body member, and presenting continuous surfaces of said body member and said bindet" member upon each side of said gasket. i
